Why do stores keep Betta fish in small containers?

Betas won't get much bigger than those containers in the time it takes to sell them, unlike the goldfish who grow quickly. Betas are lovely, come in array of species, and colours. They breathe air and don't need a filter. A glass container with the scalloped top in the floral department is a fine size for them.

I am sorry, but you are wrong.

1. If you have read about aquarium nitrogen cycle in our library, you should know there is absolutely no fish can live in a closed system without a filter system. The fish will be killed by its own ammonia toxic waste within weeks if not days.

2. Like we have pointed out in earlier posts, betta is a tropical fish, it will become sick and eventually die without a heater.

3. Yes, betta fish has a labyrinth organ which allows it to breath directly from the air, but this fact only mean you do not need an air pump. Be able to breath from the air has nothing to do with the filter system nor the heater, and the betta still need them both in order to survive.

A glass container is a death trap for any fish. You need a real fish tank of no less than 5gallon for stable water temperature, PH, hardness, nitrate concentration, etc. Fish can die easily in unstable water.
